What is the approximate solution of the linear system represented by the graph below?

The approximate solution is

(4,-1)

Step-by-step explanation:

The point of intersection of the two lines is the solution of the linear systems represented by the graph.

From the graph we can determine that each box is 2 units.

From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be

Note that since each box is two units, half way between the boxes gives one unit.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
